3 ENHANCED WASTEWATER TREATMENT THAT SAVES TIME, MONEY AND SPACE BioSphere Moving Bed Biological Systems are the latest innovation from Evoqua, a leader in fixed-film wastewater processes dating back to early rotating biological contactors from Envirex. BioSphere Biological Systems by Evoqua incorporate a newly designed biomass carrier into a moving bed fixed-film process that provides a protected, extremely high surface area environment for biofilm growth. The systems allow capacity increases of 200% or more and ensures compliance with ever-tightening permit limits all within existing plant footprint. BioSphere Biological Systems are ideal for plant upgrades, retrofits or expansions of both municipal and industrial wastewater treatment plants. The technology is cost effective and reliable. It can achieve BOD to < 5.0 mg/l, and total nitrogen (TN) enhanced nutrient performance of < 3.0 mg/l without adding tanks to an existing plant. The technology integrates into most existing activated sludge bioreactors, so project scope and duration is reduced. The small footprint required by the technology, and its ability to handle upset conditions also makes it a cost-effective, reliable solution for new plants. KEY BENEFITS OF BIOSPHERE BIOLOGICAL SYSTEMS: Cost Effective Design and implementation efficiencies ensure lower capital and operating costs than conventional alternatives. Small Footprint High-rate treatment allows for a smaller footprint than conventional processes. Flexible Design The treatment system integrates into most activated sludge bioreactors. It can also be applied as a roughing filter for pretreatment or as a post-treatment polishing bioreactor. Expandable Simple media addition allows for easy plant expansion to accommodate population growth or other needs for capacity. Stable Operation Toxic upsets and hydraulic wash out events do not affect the entire microbial population in the biofilm, ensuring smooth and rapid system recovery. Intensive and Low-Temperature Nitrification A separate microbial population held on the biomass carriers enables quantitative nitrification even at a low sludge age. An autotroph rich biofilm allows stable nitrification, even at low temperatures. Reliable Media Retention Efficient use of non-clogging wedge wire screens ensure reliable retention of the biomass carriers in the bioreactor. Durable Cover Photo: Nestled on Long Island Sound with no room for expansion, capacity at this 9.7 MGD water pollution control facility was increased by 76% while adding BNR treatment to achieve effluent total nitrogen of < 4.4 mg/l. Heavy duty carriers can exceed 20-year life expectancy, even under intense bioreactor mixing conditions. 3

4 Side-by-side testing validates performance at 800 m 2 /m 3 surface area. INDUSTRY LEADING BIOSPHERE BIOMASS CARRIERS ARE THE RESULT OF EXTENSIVE R&D TECHNOLOGY, EXPERIENCE AND PROOF AT ITS CORE At the heart of the BioSphere Biological System is a patented carrier the product of a comprehensive research and development effort. It is proven to provide 800 m 2 /m 3 of protected surface area for biomass growth. Using 3D modeling, Evoqua determined the most efficient placement of partitions to maximize surface area while ensuring sufficient space for biological growth. This efficient use of material helps make the BioSphere Biological System carrier the lowest cost-per-surface-area solution on the market. The BioSphere Moving Bed biomass carrier was subjected to a prolonged series of intense biological validation tests at a state-of-the-art Evoqua laboratory. Carbon oxidation, nitrification and denitrification tests were conducted to ensure media performance in a multitude of biological environments. The combination of 3D modeling and comprehensive validation testing has made the BioSphere Moving Bed biomass carriers an industry performance leader. Evoqua offers biomass carriers tailored for specific treatment needs. BioSphere-N, for example, excels in ammonia removal applications.

5 BioSphere Moving Bed Biological Reactor EVOQUA KNOW-HOW TAILORED FOR SPECIFIC NEEDS FLEXIBLE SOLUTIONS THAT IMPROVE EFFICIENCY BioSphere Moving Bed Biological Technology can be installed either as an integrated fixed-film activated sludge system (IFAS mode) or as a fixed-film system without activated sludge circulation (MBBR mode). Both systems utilize a unique spiral role aeration pattern that simultaneously mixes, transfers oxygen and sloughs off old biological growth. In IFAS mode, RAS is returned to the bioreactor and the suspended biomass is combined with the fixed film biomass attached to the carriers. This mode of operation: Increases plant capacity without adding tanks or plant infrastructure Enhances biological nutrient removal in new or existing applications Is a cost-effective augmentation to an activated sludge process In MBBR mode, the BioSphere Biological System uses a single pass configuration with no return activated sludge (RAS). This mode of operation: OXYGEN DELIVERY THAT HELPS OPERATORS BREATHE EASIER The BioSphere Biological System utilizes unique spacing of the aerators to create a spiral role action of the biomass carriers. This rotation is important in sloughing old growth from the surface. The uplift and downlift action also ensures good mixing and oxygen transfer through the full depth of the tank. Evoqua aeration systems are compatible with both PVC and stainless steel and are available with self-sealing diffusers to minimize piping maintenance. For added peace of mind, aeration effectiveness is documented through the ASCE certified clean water oxygen transfer tests. PILOT TESTING OPTIMIZED TO MEET UNIQUE PLANT NEEDS Not all wastewaters are the same, especially when it comes to industrial applications. Evoqua offers both bench scale and on-site pilot testing programs from its US and Singapore locations when needed to help tailor an optimal design. Reduces the suspended solids loading rate (SLR) on the clarifier Saves pumping energy by eliminating sludge recycle from the clarifier Increases the efficiency of BOD removal, roughing and pretreatment applications Is an effective lagoon system upgrade especially for ammonia removal Aeration system creates a unique biomass carrier spiral role action. 5

6 > 75% open screen area. RELIABLE RETENTION STRATEGIES Strategically-placed retention screens ensure all biomass carriers for the BioSphere Biological System remain in their respective zones for the duration of the plant s life. Screens are available in cylindrical or flat models, depending on a facility s needs and utilize either a wedge wire or perforated plate design. Each screen has a minimum 7 mm opening allowing for smooth operation with the smallest number of screens, while also creating < 2 of head loss per stage. Screen supports are designed to withstand the buoyant forces of media and accommodate the full weight of media during draining. All supports are sized by Evoqua structural engineers and supplied as integral components of each customized system. MULTIPLE CONFIGURATIONS FOR A BROAD ARRAY OF APPLICATIONS BioSphere Moving Bed Biological Systems meet a wide range of wastewater treatment needs. Nutrient Removal The BioSphere Biological System in an IFAS configuration combines attached biofilm and activated sludge systems. It is specifically designed for: Retrofitting existing plants for biological TN and total phosphorus (TP) removal Increasing plant capacity and improving effluent quality Existing Lagoons Effluent quality of lagoon systems can be upgraded by adding the BioSphere Biological System as a polishing treatment. The result is an easy-to-operate, flexible and cost-effective solution that offers: Ammonia removal from lagoon effluents Lagoon effluent BOD polishing BOD Removal The BioSphere Biological System can be configured to achieve intensive BOD removal in a very short hydraulic retention time (HRT). This solution is best suited for: Increasing the BOD removal capacity of an existing plant Compact industrial and municipal plants BOD and Ammonia Removal For COD/BOD removal and nitrification without the use of activated sludge, the BioSphere Biological System offers a configuration solution based on fixed biofilm. Low bioreactor effluent suspended solids concentrations enable the use of dissolved air flotation (DAF) or filtration systems instead of clarifiers. This configuration, which reduces treatment plant space requirements, is especially suitable for: Industrial wastewater treatment New plants with area limitation and/or wastewater temperature < 10 C 6
